TWINE FOR BINDING GRAIN.

SPECIFICATION forming part of Letters Patent No. 523,059, dated July 1'7, 1 8 94.

Application filed August 24, 1889- Serial No. 321,838. (No specimens.)

To aZZ whom it may concern.-

Be it known that I, FARMER R. WILLIAMS, a citizen of the United States, residing at Beloit, in the county of Rock and State of Wisconsin,

have invented certain new and useful Improvements in Twine for Binding Grain," of which the following is a full, clear, and exact specification.

The object of my invention is to provide a to twine suitable for use in grain-binding har vesters.

My twine consists of a paper strip wound or twisted into cylindrical form: by which I mean into such form as to present a strong I 5 and self-sustaining tube adapted to withstand severe longitudinal strains without separation of its coils or convolutions.

I am aware that an ordinary cord of fibrous material has been provided with a narrow 2o strip of paper wound helically thereon. This structure did not, however, present adistinct .or self-sustaining tube, or a tube adapted to withstand longitudinal strains except as it v was internally-sustained and strengthened by the cord, and in this regard differed mate rially from the twine which I have invented which as already indicated comprises a strip of paper wound or rolled upon itself from one of its longitudinal edges toform asubstan- 3o tially solid cord or body.

I am aware of the patents of De Gunion, No. 99,654; Tice, No. 43,874,, and Wortendyke, No. 42,896, which show and describe machines for forming cord or twine from a strip of paper 3 5 by coiling or twisting the same in such manner as to present a hollow structure with no internal support, the result being that when subjected to longitudinal strain the edges of the strip at each adjoining coil would separate. These cords differ widely from that which I have invented, consisting of a strip curled or coiled longitudinally as it were from one edge toward the other so as to present a plurality of thickness throughout its length.

Under such a construction the cord 1 s cylindrical, embodying an internal sustaining portion made up of the strip, so that it is adapted to efiectually withstand without separating or collapsing, the severe longitudinal strains to which it is subjected in practice.

In the accompanying drawings,-Figure 1 is a perspective view illustrating the initial step in the manufacture of my twine. Fig. 2 is a view illustrating the operation at a more advanced stage. Fig. 3 is a view illustrating the last step in the operation, and the finish ed cord. i

In carrying my invention into practice I provide paper in long strips of uniform width.

It may be made from any stock giving the necessary pliability and strength. I commence the manufacture by rolling or coiling the paper from one edge toward the other, as indicated in Fig. 1. until it forms a substantially solid cylindrical body with a plurality of layers or convolutions, as shown in Fig. 2. If made of suitable soft stock it willin this form answer a good purpose but be somewhat deficient in pliability. The pliability and strength may be increased by twisting the body, as shown on the right hand in Fig. 3, thereby compacting the same and reducing its size.

It is to be notched that in my twine the paper is coiled or lapped in such manner as to present at all points a practically solid body, in several layers; that the edges of the paper strip extend substantially in line with the axis of the twine so that it will resistlongitudinal strains to advantage; and that its coils orconvolutions cannot be pulled apart lengthwise of the twine as in the case of a strip wound spirally at a sharp angle to the axis of the twine.

What I claim is- A twine consisting of a paper strip wound resist longitudinal strains without untwistin g or rupturing the strip.
